Select the set in which the numbers are related in the same way as the numbers of the given sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
(111, 117, 123) (169, 200, 231)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. (125, 135, 145).
The logic used here is:
(111, 117, 123)
111 + 123 = 234
234 ÷ 2 = 117
(169, 200, 231)
169 + 231 = 400
400 ÷ 2 = 200
Similarly,
(125, 135, 145)
125 + 145 = 270
270 ÷ 2 = 135
Hence, option 3 is the correct answer.
